Hippocrates, (born c. 460 BCE, island of Cos, Greece—died c. 375 BCE, Larissa, Thessaly), ancient Greek physician who lived during Greece’s Classical period and is traditionally regarded as the father of medicine. It is difficult to isolate the facts of Hippocrates’ life from the later tales told about him or to assess his medicine accurately in the face of centuries of reverence for him as the ideal physician. About 60 medical writings have survived that bear his name, most of which were not written by him. He has been revered for his ethical standards in medical practice, mainly for the Hippocratic Oath, which, it is suspected, he did not write.
Technical medical science developed in the Hellenistic period and after. Surgery, pharmacy, and anatomy advanced; physiology became the subject of serious speculation; and philosophic criticism improved the logic of medical theories. Competing schools in medicine (first Empiricism and later Rationalism) claimed Hippocrates as the origin and inspiration of their doctrines. In the 2nd century CE, the physician Galen of Pergamum developed his magnificent medical system, a synthesis of preceding work and his own additions that became the basis of European and Arabic medicine into the Renaissance. Galen was argumentative and long-winded, often abusive of contemporaries and earlier physicians, but at the same time, with exaggerated reverence that ignored five centuries of progress, he claimed that Hippocrates was the source of all that he himself knew and practiced. For later physicians, Hippocrates stood as the inspirational source, while the more difficult Galen offered the substantial details.
